------------------------------------------------------------
The Foreign Intelligence Surveillance Act of 1978 (FISA, Pub. L. 95–511, 92 Stat. 1783, 50 U.S.C. ch. 36) is a United States federal law that establishes procedures for the surveillance and collection of foreign intelligence on domestic soil.
FISA was enacted in response to revelations of widespread privacy violations by the federal government under President Richard Nixon. It requires federal law enforcement and intelligence agencies to obtain authorization for gathering "foreign intelligence information" between "foreign powers" and "agents of foreign powers" suspected of espionage or terrorism. The law established the Foreign Intelligence Surveillance Court (FISC) to oversee requests for surveillance warrants.
Although FISA was initially limited to government use of electronic surveillance, subsequent amendments have broadened the law to regulate other intelligence-gathering methods, including physical searches, pen register and trap and trace (PR/TT) devices, and compelling the production of certain types of business records.
FISA has been repeatedly amended since the September 11 attacks, with several added provisions garnering political and public controversy due to privacy concerns.
== History and background ==
The Foreign Intelligence Surveillance Act (FISA) was introduced on May 18, 1977, by Senator Ted Kennedy and was signed into law by President Jimmy Carter on 25 October 1978. The bill was cosponsored by nine senators: Birch Bayh, James O. Eastland, Jake Garn, Walter Huddleston, Daniel Inouye, Charles Mathias, John L. McClellan, Gaylord Nelson, and Strom Thurmond.
The FISA resulted from extensive investigations by Senate Committees into the legality of domestic intelligence activities. These investigations were led separately by Sam Ervin and Frank Church in 1978 as a response to President Richard Nixon's usage of federal resources, including law enforcement agencies, to spy on political and activist groups. The law itself was crafted in large part in closed door meetings between legislators and members of the Justice Department.
The act was created to provide judicial and congressional oversight of the government's covert surveillance activities of foreign entities and individuals in the United States, while maintaining the secrecy needed to protect national security.
=== Warrantless domestic wiretapping program ===
FISA came into public prominence in December 2005 following an article in The New York Times that described a program of warrantless domestic wiretapping ordered by the Bush administration and carried out by the National Security Agency since 2002; a subsequent Bloomberg article suggested this may have already begun by June 2000. Attorney General Alberto Gonzales later confirmed the existence of the program, which was codenamed Stellar Wind.
Without obtaining a FISA warrant, the NSA monitored phone calls, Internet activities, text messages, and other forms of communication involving any party it believed to be outside the U.S., regardless of whether part of the communication took place domestically. The Bush administration initially defended the program as an extension of executive authority; amid public, political, and legal pressure, the program was ended in January 2007 and the government announced it would seek warrants from the Foreign Intelligence Surveillance Court (FISC).
=== Section 702 ===
Following the controversy over Stellar Wind, Congress later legalized a form of that program in Section 702. Between 2020 and early 2022, Bureau personnel conducted more than 278,000 searches of surveillance databases that did not meet legal standards.
Following the December 2019 DOJ Inspector General report, FBI Director Christopher A. Wray announced corrective actions to FISA policies and procedures. NBC News reported in July 2023 that FBI queries of foreign spy data had fallen 94% following reform implementation.
A proposed warrant requirement for such searches failed by a single vote in the House of Representatives.
== Provisions ==
The subchapters of FISA provide for:
Electronic surveillance (50 U.S.C. ch. 36, subch. I)
Physical searches (50 U.S.C. ch. 36, subch. II)
Pen registers and trap & trace devices for foreign intelligence purposes (50 U.S.C. ch. 36, subch. III)
Access to certain business records for foreign intelligence purposes (50 U.S.C. ch. 36, subch. IV)
Reporting requirement (50 U.S.C. ch. 36, subch. V)
=== Electronic surveillance ===
Generally, the statute permits electronic surveillance in two different scenarios.
==== Without a court order ====
The President may authorize, through the Attorney General, electronic surveillance without a court order for the period of one year, provided that it is only to acquire foreign intelligence information, that it is solely directed at communications or property controlled exclusively by foreign powers, that there is no substantial likelihood that it will acquire the contents of any communication to which a United States person is a party, and that it be conducted only in accordance with defined minimization procedures.
